Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00609 |
| Opus 5.5 | $0.00015 | $0.00244 |
| Sonnet 5.5 | $0.00008 | $0.00122 |
| Haiku 4.5 | $0.00004 | $0.00061 |
Grade A, and why
veh-trailer-only-inspection scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trailer-Only Inspection (Standalone Trailer)
A standalone trailer (not coupled to a tractor) still requires periodic inspection. The carrier owns the inspection responsibility.
Annual inspection (same as tractor)
- Required every 12 months
- Conducted by a qualified inspector
- Covers brakes, lights, hubs, structure, body, suspension
- Certificate retained in trailer file
Pre-trip inspection of trailer
- Driver coupling to a trailer inspects the trailer at coupling
- Brake hose connections, lights, glass, mirrors
- Body integrity, latches, doors
When trailer is parked
- Not subject to daily DVIR (only when in operation)
- Annual inspection still required regardless of parking time
- Lights, tires, structure visible from outside should be checked weekly
Trailer ownership scenarios
- Owned trailer — carrier is responsible for inspection
- Leased trailer — depending on lease, lessor may be responsible (read the lease)
- Hired trailer (drayage, intermodal) — operator/owner responsible
Trailer maintenance records
Required per § 396.3:
- Last annual inspection
- Last preventive maintenance event
- Last repairs
- Hub lubrication
- Lighting and electrical work
Inspection at non-traditional times
- Before long-term storage (180+ days inactive)
- After unusual wear pattern noticed
- Following accident or impact event
- When carrier identifies trailer in trouble pool
Compass Vehicles tracking
- Trailer fleet visible in main vehicle inventory
- Annual inspection due tracked per VIN
- Coupling event auto-logs pre-trip
- Inactivity flag for trailers inactive 180+ days
CFR citations
- 49 CFR § 396.17
- 49 CFR § 393
- FMCSA Appendix G
How Compass surfaces this
Searchable in Compass Ask. Runs against carrier fleet data when invoked from the relevant tracker. Read-only; no actions without explicit user approval.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

veh-trailer-only-inspection is a skill published in the GitHub repository x3allamerican/skills (3 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 38 tokens to every session and 609 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

Use this skill to deterministically find license information for Python packages by checking PyPI metadata first, then falling back to Git repository LICENSE files using shallow cloning.
Audit and normalize SPDX license headers before releasing or open-sourcing a repository
Use REUSE when an agent needs file-level licensing clarity instead of guessing from a single top-level LICENSE file. The agent checks compliance, adds or verifies SPDX headers, pulls missing license texts into LICENSES/, and produces a concrete remediation list or SPDX export.
